Does the battery life increase with subsequent chargings because I am getting nowhere close to 10 hours? I have it at about half brightness and its discharging quite quickly with little multitasking. How much do you get?
This is the first time I'm charging it by the way.

No. This will not happen with LiIon/LiPoly batteries. In fact they lose a wee tiny bit of capacity on every subsequent charge.
I get about 4-8h of battery life, depending on what I do.

I get 7-9 hours with the brightness at 0-25%(no or little gaming) This seems to inline with what I've seen at Anandtech
I've had noticeably better battery life after a few charges. But then again I've changed a few settings or it could be just placebo.

How is the battery holding up for most folks?
I've been using Atrix for a few hours tonight (perhaps a bit more than normal use was on my Nexus) and I've already used 50%. Thats pretty crappy for whats proclaimed to be a large, long-lasting battery.
What should I be doing to improve battery life on this device?
Thanks.
I've seen the same poor battery performance. I'm hoping after being on the charger all night I'll see the battery performance that I've read about.

It's called "New Battery Syndrome give it a week, you will settle into your normal usage pattern and you will really see fantastic battery life.
Pretty much, you have a new toy, you want to play with it as much as possible, thus you run it more than you may have used your previous devices thus effectively running the battery down faster.
Mine seems to be pretty great. Have had the display on for about two hours straight and it only drained 20%
naturefreak probably nailed it. most batteries seem to last longer after they've been discharged and recharged a few times.... on top of playing with it for probably just about the entire day..... BOUND to see less-than-expected battery life.
Whenever I check my battery status, my display is always at 45%. Is this normal? I still get good battery life, I think. For example, I been unplugged for 6h and 18m and I'm just at 70% battery remaining.
I don't know what to tell you; if you aren't doing a lot of CPU intensive tasks, the battery should bbe good for hours.

that's kinda strange, not cuz you are always stuck but because you are showing 45%. I thought the atrix only measures by 10s.

That is exactly what I was thinking. I've never seen anything but increments of 10%.
No....I'm not talking about my battery percentage, I'm talking about my display percentage. Its always the higher of the four...wifi, phone idle and cell standby is always low, like in the single digits low. But the display is always high. Like for example I woke up this morning, checked what was consuming battery and the display was at 65%. If the phone was sleep for the past 4-5 hours thus the display not being on, the display shouldn't be consuming that much battery, so I thought.
I still get great battery life. Im just wondering if anyone else display is also consuming a lot battery and what could be causing it.

Ahhh, ok. I get what you mean now. This is normal for most Android phones with large (4" or bigger), bright screens. As long as you are getting good battery life you are fine. I'm assuming you keep your brightness set to automatic?

Considering you are getting good battery life and your display has that high of a percentage after "sleeping" that long is a good thing. That just means the other processes are running efficiently. You should always expect the Display to take up at least 60% of your battery, especially after a full cycle. What really matters is actual runtime.

Ok...thanks. I was just wondering.
Hi,
First of all...I love this phone. Now that I have gotten that out of the way.
When I first got the phone for the first week or so, after taking it off the charger it would stay at 100% for roughly 4 hours even with minimal usage. I kind of like that, makes me feel like the phone has superior battery life.
Today, it started dropping from 100 like most phones I used in the past. Within an hour or so I was down to 96%.
What experience have you guys had with it staying at 100? How long do you guys generally stay at 100?
Thanks

Never 4 hours, but usually 15-30 mins of using it steadily in the morning.
The OS is probably building more status on battery usage and capacity and is now showing a more accurate representation of your battery level. Supposedly on each reboot the OS generates new battery stats.

This is due to the battery meter being inaccurate out of the box. It will adjust after a week or so.

But I used my iphone at work to watch videos, ect while there is downtime. I usually watch while it's also on the charger
For the Note series, does anyone know if that "kills" my battery for long term?
I know you can replace battery, but just wondering for future use.
Thanks.
Issue with battery drain due to android system is real
All three people I know that just got the Note 4 were experiencing the same issue I had with excess battery drain with the always generic "android system" taking more battery than anything else including the screen.
I downloaded an app called "System Tuner" and looked the CPU% for Android system and it was a constant 3-4% when the phone was otherwise idle.
I found a post at http://support.t-mobile.com/thread/80459 where they were experiencing the same issue (lose around 12% battery an hour with android system taking a huge chunk of battery). The person from that post was able to address the issue by turning location off, rebooting, turning location on, and rebooting again. After I did this I saw Android system idle at ~0.6% - 1.1% instead. So far I'm getting much better battery life but I'll need to give it some time to know for sure.
Hope this helps!
mine took about 2 full days for everything to finish syncing, downloading, indexing, etc. I had books, news articles, pinned music from google play, etc.
Once that happened, everything is now "normalized" and I'm getting better battery life than I was with the note 3.

Short answer: Maybe, it depends on how you are doing it. Using it while it is charging is not necessarily bad but watching videos and keeping it plugged in while the cell voltage is pegged at 100% will likely deteriorate your battery faster.
Long answer + tips:
Lithium ion batteries are great - they are light, can be made very thin and have excellent energy density but they are also very finiky.
Things to avoid doing with a lithium ion battery
-Charging to 100%, leaving it plugged in overnight is a poor practice(high cell voltages reduce the service life*, stopping the charge at 90%[4.10v] can double the service life, stopping the charge at 80%[4.00v] can quadruple the service life.*)
- Discharging the battery to below ~20% (Li-Ion batteries are somewhat sensitive to deep discharges)
-Charging/exposing Li-Ion to elevated temps or below freezing.
*service life is defined by when a battery can only retain 70% of its rated capacity. Most consumer batteries used in mobile devices have a service life of 500 charge discharge cycles.
It is not uncommon for batteries to lose 30% capacity in 1.5 years or less. Changing your charging and handling habits can double or quadruple a batteries life span.

LOL your picture took up have my damn screen on my 1080p laptop with 15.7 in screen. It was crystal clear too.
On my 2nd charge, auto brightness. Pretty freakin' amazing battery life....
15.5 hours off the charger with 8+ screen on time!
I got awful battery life on the first charge cycle. It drained 50% overnight. 2nd charge has lasted amazingly long and I still have 64% after 12hrs of average use.
First charge. Battery life has been phenomenal. Brightness on auto.
Did u use any power saving features to achieve that time?
Did u use any power saving features to achieve that time?
Definitely improve battery with recent update and I'm a power user
After the latest update
I dont know why but my phone goes from 100-90 in less than a hr with minimal use while the screen is set at auto, also in the leaving it unplugged in the night the battery also drains like 5 points.
I've been at full brightness and using the hell out of it non stop so far, and I'm at 35% with screen on time at 3hrs 40 min.

Hello,
I read in the internet that is not recomended charge 100% the phone's battery. It's about the battery life. I want to know if it is really true....
Sorry my bad english :cyclops:
Maybe if you want to keep the phone for 5 years you'll notice a difference in battery life by keeping it charged between 20-80% but rarely does anyone do this.
True? Yes, it is. In the same way that it's true that a (properly done) overclock on a CPU will shorten it's lifespam. Yes the overclock will shorten the CPU's lifespam, from 20 years to maybe 15.
Your battery will degrade regardless but by the time it becomes an issue, you'll probably have moved on to a new phone anyway.

But charging the battery in only 80% means that I will have less SOT before charge again

The theory behind this apparently is that how battery likes to be in certain battery levels based on the voltage.
Based on what I understand, the phone/battery likes it better if battery is not less than 20 and not more than 80.
This means that if you charge between 20 - 80, you can have a lot more charge cycles as compared to 0 - 100. This could also mean that the battery can last longer in terms of longevity.
But as mentioned, not many people does that unless they are looking to keep their phone for more than 3 years.
These are based on my limited understanding and my own experiences.
You can google battery university if you need more info.

Most of the information here is correct I have an am always doing battery tests research and such
80% and 20% are the magic number for maximum overall life of a battery...
Also no on mentions heat and cold also degrades the cells inside
I also recomend if you make it through the day shutting off fast charge......
If you think about it it is simmilar to any other battery,
Take a car for example I know i know lead battery vs lith ion but slow charging is the best method for any types of battery life in the long run.... it does not excite any of the ions as much as fast charging......
Fast charging on auto batteries is what we call a surface charge it quickly excites the electrons for a quick zap of juice but then over all that spreads out among all of the rest of the electrons quickly draining and shortning over life....
Slow charge generates less heat as well as does what we call a deep charge....Which is better of coarse I have had automotive batteries say like in my eclipse its 9 years old and it was a 800 amp battery and even after 9 years now
It retains over 650 amps on battery tests because i slow charge it once a month for a couple days be it need it or not..
Also if you guys are over worried and snap dragon try part cyborg rom the engineering kernel used by samdung only allow for a 80% charge.....I get more screen on time than stock on less charge because it is optimized so well....any where from 6 to 8.5+ hours and that is more than enough more my needs....
Also wireless chargers generate heat which degrade life on batts cells.....
I can get way more into detail on any of these if any one wishes

Have just started reading about s8 stuff and have not rooted yet. Does the kernel allow you to set maximum charge? I remember back on sgs1 specific kernels allowed this but haven't seen it much since then

no samsung preset it at 80% and since the bootloaders locked no way to modify it
Ahh I see. Thanks for clearing that up. Looks like since I'm on oreo now I'm stuck without root so I won't be playing with any of that stuff. Have a good one!
